The primary aims of this project were to install a new sensor system with data acquisition on the I-35 Walnut Creek Bridge (WCB) in Purcell, OK, and to continue the development of algorithms that will implement structural health monitoring on that...

A prototype in situ fatigue sensor has been designed, constructed and evaluated experimentally for its ability to monitor the accumulation of fatigue damage in a cyclically loaded steel structure, e.g., highway bridge. The sensor consists of...

In 2008, the INCOG Economic Development District was designated by the Economic Development Administration. INCOG is submitting this updated Comprehensive Economic Development Strategy (CEDS) as we reevaluate and establish the regional economic...

The objective of the research is to investigate the effects of the admixture IPANEX in concrete bridges. IPANEX, as an admixture manufactured by IPA systems prevents water and chloride-ion penetration thus protecting the reinforcing steel against...

Research reported upon at the symposium focused on the following: types of FDD reservoirs, depositional settings, diagenetic history, reservoir characterization, and enhanced oil recovery. In describing the various FDD petroleum reservoirs in the...

The primary objective of this study is to evaluate the effect of durability of cementitiously stabilized subgrades in Oklahoma. To that end, five different types of soils, namely, Port series (silty clay with sand), Kingfisher series (lean clay),...

The purpose of this report is to present the results of our research and development of OKCARS: Oklahoma Collision Analysis and Response System. By continuously monitoring traffic intersections to automatically detect that a collision or...
